Center the map on a specific marker on page load -

In this tutorial, you’ll see how to center the map on a specific marker when loading the map page.

For this to work, you’ll have to add the attribute post_id to the URL. For example, if you want to navigate from your website’s homepage www.website.com to your map page www.website.com/map, you’ll have to add the attribute post_id to that URL with the real post ID as its value. In our example, your URL should be www.website.com/map/?post_id=15 where 15 is the real post ID.

Edit the file “functions.php” of your theme/child theme and copy/paste the following code in it:

function cspm_center_map_on_specific_post($default, $map_id){
	
	if(isset($_GET['post_id'])){
		
		$post_id = esc_attr($_GET['post_id']);
		
		$latitude = get_post_meta($post_id, CSPM_LATITUDE_FIELD, true);
		$longitude = get_post_meta($post_id, CSPM_LONGITUDE_FIELD, true);
	
		$output = "
		setTimeout(function(){
			cspm_center_map_at_point(plugin_map, map_id, '".$latitude."', '".$longitude."', 'zoom');
		}, 500);";
		
		echo $output;
	
	}
	
}
add_filter('cspm_after_map_load', 'cspm_center_map_on_specific_post', 10, 2);
